Exchange rate volatility and bilateral agricultural trade flows: the case of the United States and OECD countries
The abandonment of fixed exchange rate systems has caused exchange rate movements to become a major concern for traders, policy makers and researchers. During the previous four decades of floating exchange rates, numerous studies have been conducted to determine whether exchange rate volatility affected international trade flows. Researchers have not yet reached a general consensus as to the magnitude and direction of the impact of exchange rate volatility on trade flows. This study documents the effect of exchange rate volatility and real exchange rates on bilateral agricultural exports, imports and total trade flows between the United States and OECD countries. The effect of exchange rate volatility is estimated both separately from and in combination with the real exchange rate. In addition, implementation of Free Trade Agreements (FTAs) and use of the Euro as a national currency (Euro) are included as dummy variables and their effect on trade flows is determined. This study uses panel data, which contains 28 cross-sections and 1148 observations, for bilateral trade flows between the United States and OECD countries from 1970 to 2010. Data analysis is performed as guided by the gravity model which assumes trade flows to be directly proportional to economic mass and inversely proportional to geographical distance. Based on the gravity model, the ordinary least squares procedure is applied as the fixed effect one-way procedure for panel data. Effects of exchange rate volatility and the real exchange rate on agricultural, non-agricultural and total exports, imports and trade (exports +imports) flows were found to be statistically significant and negative. Although we were able to replicate the reportedly established notion that exchange rate volatility has an adverse effect on international trade flows, the negative effect that the real exchange rate has on trade flows is a novel finding and bears further investigation. It is found that exchange rate volatility has a greater impact on the agricultural sector, while the real exchange rate has a greater impact on the non-agricultural sector. Effects of FTAs and the Euro are always positive, with FTAs having a greater impact on the agricultural sector and the Euro on the non-agricultural sector
Impact of coordinated asset transfers and asset ownership on poverty reduction, women's empowerment, and child education: evidence from Zambia and Tanzania
This dissertation assesses the impact of coordinated asset transfers and asset ownership on poverty and food security, women’s empowerment, and child education in Zambia and Tanzania. In contrast to the traditional view of assets uniformly improving child development outcomes through wealth effects, Chapter 2 assesses whether different types of assets have differential effects on child education. I find that household durables and housing-quality characteristics have the expected positive effects, but agricultural assets have adverse effects on highest grade completed and test scores. I extend the agricultural-household model by explicitly including child labor to portray a theoretical framework for different assets to have differential effects and use three waves of National Panel Survey data from Tanzania to estimate empirical relationships. I correct for the endogeneity of assets and control for time-invariant unobservable by using the Hausman-Taylor instrumental variable (HTIV) method. Further examination reveals that the negative effect of agricultural assets is more pronounced among boys, rural children, poor children, and children from farming households. These conditions may raise the opportunity cost of schooling and result in weaker education outcomes.
Building on the finding that different assets have differential effects, the third and fourth chapters assess the impact of an intervention that provides livestock, support services, and associated training to impoverished households in Zambia. In Chapter 3, I confirm previous findings that physical asset transfers increase income and consumption expenditures. Then I examine the practical significance of the increase in expenditures to assess whether it is large enough to trigger changes in consumption patterns or in subjective assessment of wellbeing status. Changes in composition of expenditures, composition of diet, and subjective self-assessment of poverty all suggest that the intervention contributes to a growing sense of economic security and a practically significant change in wellbeing. As transfers included three different types of animals – dairy cows, meat goats, and draft cattle – I am able to discern that the impact does differ by the types of assets transferred. Examination of changes in the composition of consumption shows substantial effects on poverty and food security starting within six months of asset transfers. Persistence of the impact through the next 18 months of the study period indicates that livestock transfers can have a sustained effect on poverty and food security.
In Chapter 4, I assess the impact of the same livestock transfer and training intervention on intra-household ‘decision-making’ over different farm household activities and resources. Using a two-period panel dataset, I use decision-making abilities as empowerment measures and find that the intervention significantly improved both women’s and men’s empowerment by expanding the scope of joint decision-making in household activities. In particular, the intervention helped increase the proportion of joint decisions by 17% in all household activities considered and both men’s and women’s independent decisions decreased by as much as 9%. Similar pattern follows when household activities were categorized to ‘treatment related’ and ‘other’ activities; women’s and men’s joint decisions increased at the expense of their independent decision-making participation. I confirm that the finding is consistent with the prediction of the Nash bargaining model because transferring economic resources to women or men leads to Pareto optimality in intra-household resource allocation only through co-operation between men and women
Pesticides handling practices among potato growers in Kavrepalanchok, Nepal
The rate of pesticide application in the agricultural field is surging. Farmers are getting exposed to pesticide hazards from the misuse and unsafe handling of pesticides. The study was conducted among 101 potato growers in Kaverpalanchok district of Nepal in 2018. The objective of the study was to assess the knowledge, status, and pesticide handling practices among potato growers. Around 94% farmers applied pesticides against early and late blight. Only 5% growers treated seed before potato sowing. About 93 and 73% farmers sprayed pesticides 2-10 times/season into the field and spent 2-6 hours/pesticide spray respectively. More than 2/3rd growers did not read the pesticide labels, and nearly 95% growers received information on pesticide applications from agrovet rather than authorized government bodies. Only 13% farmers had received Integrated Pest Management (IPM) training. However, 1/4th of them had practiced IPM techniques. The majority of the growers used masks, rubber boots, and long-sleeved clothes during pesticide handling. Nearly 2/3rd growers threw pesticide containers anywhere in the environment. Concerned authorities should provide IPM training, skill-building programs on pesticide handling and awareness on waiting period and environmental hazards to avoid pesticide risk

437-439The formation constants of 1 : 1 and 1 : 2 binary (Cu-A and Cu-A2) and 1: 1 : 1 ternary (Cu-A-L) chelates [where A= 4-amino-5-mercapto-l,2,4-triazole (AMT) or 4-amino-5-mercapto- 3-methyl-l ,2,4-triazole (AMMT) and L= ethylenediamine (en); 1,10-phenanthroline (Phen); 2,2'-bipyridyl (Bipy), o-phenylenediamine (OPDA); glycine (Gly); o-aminophenol (o-AP); catechol (Cat); oxalic acid (Oxa) or thiodiacetic acid (TDA)] have been determined potentiometrically in aqueous medium. The ligands AMT and AMMT behave as primary ligands in presence of en, Gly, o-AP and Cat, while in presence of Phen, Bipy, NTA, IMDA and Oxa, they act as secondary ligands. They coordinate simultaneously in presence of OPDA and TDA. The overall stability constants, Log βAL, are discussed in terms of the basicity of ligands, statistical aspects, electrostatic interaction, metal-ligand π-interaction, denticity, nature of donor sites and stereochemical aspects

Clinical and microbiological observational study on AmpC β-lactamase-producing Enterobacteriaceae in a hospital of Nepal
Limited information is available regarding AmpC β-lactamase (ABL)-producing Enterobacteriaceae compared to extended-spectrum β-lactamase-producing enterobacteria. Since ABL-producing organisms are often resistant to multiple antimicrobial agents, therapeutic options against these pathogens are limited. Among 230 clinical Enterobacteriaceae isolates, 64 (27.8%) were found to produce ABL in our study. Escherichia coli (83.9%) was a predominant pathogen, followed by Citrobacter freundii (5.2%). A significant proportion of ABL-producing isolates (81.3%) were found to be multidrug resistant against commonly used antibiotics. Univariate analysis showed that prior history of taking antibiotics (odds ratio [OR], 5.278; confidence interval [CI], 2.838-9.817; p < 0.001) and being inpatients (OR, 4.587; CI, 2.132-9.9; p < 0.001) were associated with ABL positivity. Regular antimicrobial resistance surveillance for ABL-producing Enterobacteriaceae is warranted for proper antimicrobial treatment strategy and policy making due to ABL-positive infections
